To all whom it may concern: y

Be it known that I, HUBERT GASPAR KR-- TEN, a subject of the King of Prussia. and residing at Aix-la-Chapelle, in the Kingdom of Prussia, Germany, haveinvented an Improvement in Water-Closets, of which .the following is a specification.

My invention relates to water-closets; and it is designed to afford a sufficient water-seal for closets both when in use and when disused without interference with the movements of the eXcreta and their entrance into the drainpipe, and to provide a more efficient iiush than hitherto, and to simplify the regulation of the supply of the flushing-water as much as possible. with special reference to the adaptation of the improved closet to be used alternatively as a urinal.

rlhis invention consists in certain novel combinations of parts, hereinafter set forth and claimed.

A sheet of drawings accompanies this specification as part thereof.

Figure l of the drawings represents a nearly vertical transverse section; and Fig. 2 a vertical longitudinal section of my improved closet, the plane of each being indica-ted by a dotted line across the other figure. Fig. 3 represents a section in the same plane as Fig. 1,'illustrating a modication.

The closet consists of an outer funnel, A, in which is placed a second somewhat narrower funnel or bowl, B, which rests upon a diaphragm or bottom, c', cast with the outer funnel, A. The inner funnel or bowl, B, is thus supported vertically and laterally without the aid of ilanges or the like thereon, While the outer funnel is at the same time adapted to be hung by top flanges on it from the top of the closet-casing or to support the latter, as occasion may demand. The bowl B is also thus adapted to be made with rolled edges, forming tubular rims b c at the top and bottom. The rim bis perforated at its lower side with numerous holes, and the rim o has a slot running completely round its inner face, or may be perforated on its inner face with a large number of holes placed closely together. Both rims communicate with each other by means of a pipe 'or channel, d, conveniently cast with the pan.

The discharge-mouth of the bottom or diaphragl'n c of the outer pan is formed into a short depending neck, o, to which is hinged a iiap valve or trap, e, provided with a high rim. This trap is operated through a connecting-link by a weighted lever, f, and a rod, g, which is attached to the rear edge of the seat C. The seat is made to pivot upon a central axis, so that when sat upon the forward part depresses and the hinder part rises, operating the rodv g.

On the upper part offunnel A is situated a bridge, z, or tube t2, upon or within which is placed a strong tube, t', Figs. l and 3, made of very soft indiarubber, but which at the same time is capable of retaining` the waterpressure, and which is in communication with the service-pipe and the rim'b. To the lower surface of the seat-board is fixed a block, h or h2, above the before-mentioned india-rubber tube, where it preferably rests upon a pistonvalve piece, k, Fig. 3, which by its downward pressure can compress and close the indiarubber pipe.

When the closet is not used, the front part of the seat is raised by the counterbalance-weight on the lever f, the aforesaid valve-piece 7c is depressed, and the supply of water is thus interrupted.

In that arrangement of the elastic flushingtubet' shown in Fig. l the tube lies uncovered upon a bridge, and is acted on directly by said block 7L as a valve-piece, to interrupt the supply of water. Eitherv arrangement may be used to effect this result.

When the closetis in use, the seat is pressed downward at the front, and thus turned upon its central axis, lifting the back of the seat as aforesaid. In consequence of this movement the lower closing-trap or flap-valve e is turned through a right angle, so that it hangs vertically, and the escape of the eXcreta from the neck o is thus unobstructed. At the same time the block h or h2, fixed to the lower side of the seat C, is lifted sufficiently to free the indiarubber tube t' from pressure. The water now enters the two'rims, from the upper one of which it escapesin the form of separate sprays, watering the walls of the inner pan, and from the lower one it escapes in horizontal sprays, which unite to close the bottom of the oritice with a water-veil. The effects produced are, first,'the walls of the bowl B are constantly IOO watered and rendered slippery, thus preventing the adhesion of the excreta; second, and moreparticularly during the use of the closet,

when the protection of the flap valve or trap 5 e is removed, a water veil or cover is formed above the mouth of the bowl, thus preventing the rise of gases from the drain-pipe, but not' the escape ofthe excreta. Then the closet is no longer used, the seat goes back into its former position. The india-rubber tube is again pressed together and the supply ofv The trap or flap valve c is on its rear edge, (see Fig.2,) lifting the rod g enough to partly lower the trap e and fully releasing the ilushing-pipe t', so that there shall be a free iiow of the flushing-water until (Represented in Figs. 1 and 2.)

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what l claim ism l. In a water-closet, au outer funnelhaving a fianged upper end to coact with the top ot' the closet-easing and an apertured diaphragm the seat is lowered to its normal position.

or bottom, in combination with an inner funnel or bowl supported vertically upon said bottom and laterally by the upper end of said outer funnel, substantially as herein specified.

2. In combination with an outer funnel havingr an apertured diaphragm or bottom, an inner funnel or bowl supported vertically upon said bottom and laterally by the upper end of said outer funnel, and constructed with tubular rims at its respective ends, having suitable water-outlets, and connected with the Aflushing-pipe and with each other, substantially as herein specified.

3. In a water-closet adapted to be used as a urinal, the combination of a seat having pivots midway between its front and rear edges, and adapted also to turn back upon its rear edge, a connection near the latter with a water-seal trap, a water-cutoff block carried by the seat behind said pivots, an elastic flushing-pipe supported horizontally beneath said block, an inner funnel or bowl provided with water-outlets, and an outer funnel having a diaphragm beneath said bowl, constructed with a depending neck to coact with said trap, substantially as herein specified.

In testi m ony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
